GERHARD HAGENMEYER, OF BIG RIVER, CALIFORNIA.

IMPROVEMENT IN GREASE-CUPS.

Specification forming part of Letters Patent No. 53,973, dated April 17,1866.

To all whom it may concern:

Beit known that I GERHARD HAGENMEYER, of Big River, in the county ofMendocino and State of California, have invented a new and ImprovedGrease-Cup; and I do hereby declare that the following is a full, clear,and and exact description thereof, which will enable others skilled inthe art to make and use the same, reference being had to theaccolnpanying drawings, forming part of this specication, in which-Figure l represents a vertical section of this invention. Fig. 2 is apartial side elevation of the same. Fig.3 is a transverse section of thesame, taken in the plane indicated by the line m, Fig. 1. Fig. 4 is asimilar section in the line y y, Fig. 1. Fig. 5 is an end view of one ofthe valve-seats.

Similar letters of reference indicate like parts.

This invention relates to an oil or grease cup, which is provided withtwo conevalves, the stems of which are connected so that they arecompelled to turn together, but free to move a short distance toward orfrom each other. Y These valves close into corresponding seats, and fromtheir peripheries project studs, which work against circular inclined orspiral planes surrounding the seats, and arranged so that the highestpart of one of these spiral planes is in line with the lowest part ofthe other, in such a manner that when the valves are subjected to theaction of a suitable gearing, which has a tendency to keep the sameclosed, by turning the valves one will open when the other closes, andvice versa, and the globe of the grease-cup is alternately brought inconnection with the supply-cup and then with the steam-chest or otherpart to be lubricated.

A represents my grease-cup, which is constructed in the usual form orshape, and composed of the supply-cup a and the globe b, which is fitted4into the stem or shank c, that is intended to screw into the part to belubricated. This grease-cup is provided with two valves, f f', and theupper end of the stem of the valvef is tted into a socket in the bottomend of the Valve f', and a pin, d, forms the connection between the twovalves. This pin passes through the socket ofthe valve f and through aslot in the stem of the valve j', so that the two valves are compelledto turn together, but

free to rise and fall a short distance,one independent of the other. Thestem of the Valve lf extends up through the supply-cup a, and

it bears a handle, g, by means of which the valves can be turned ineither direction, and a spring, 7c, has a tendency to force the valvesup, the valve f being closed by the pressure of the steam. The valvefcloses into a seat, e', on the bottom end of the screw-shank of thesupply-cup, and the valve f into a seat, c, at the bottom end of thescrew-shank of the globe b, and both these seats are surrounded bycircular inclined or spiral planes z' fi', and pins L h', projectingfrom the peripheries of the valves, bear against these spiral planes.Said spiral planes are so situated that the highest part of the plane t"is opposite the lowest part of the plane fi, and vice versa.

The operation is as follows: When the handle 7 is turned either wayone-half turn the pin 7L will lirst descend the spiral plane t', and thepressure of the steam closes the valve f, cutting off the communicationbetween the reservoir and steam-chest. The, pin It will then ascend thespiral plane t, forcing the valve j* olf from its seat and openingcpmmunication between the supply-cup and the globe. When the globe isfull the handle g is turned again one-half turn either way, the pin hdescends the spiral plane t', allowing the valve ff to closel by theaction of the spring lc, and the pin 71, ascends the spiral plane t',forcing the valve f oli from its seat a-nd opening communication betweenthe globe and the steam chest or other part to be lubricated. A suitableventvalve, j, on the side of the globe permits the steam from theinterior of said globe to escape when the valve f is closed and thevalve f opened. This vent-valve is made to open and close automatically,or it can be operated by hand.

What l claim as new, and desire to secure by Letters Patent, is-

The valves ff, spiral planes i i', and pins h h', in combination withthe supply-cup a and globe I), of a grease-cup, constructed andoperating substantially as and for the purpose described.
